heat barrier

Whether your vehicle has a carburetor or fuel injection, vapor lock can bring it to a standstill, causing hours of frustration. If you’re a racer, it can put the car on the trailer well before you’re ready to leave the track. But proper use of thermal barriers can prevent vapor lock, no matter how hot the day gets.

Vapor lock happens when the temperature of the fuel heats up enough to transform it from liquid to vapor. And since fuel pumps are designed to pump liquid, not air, vapor lock effectively starves the engine of fuel. Without the proper volume or pressure of fuel, the car will run rough or completely stall. Vapor lock typically happens during summer months, when high outdoor temperatures are combined with high engine and exhaust heat. And high altitude also makes a vehicle more prone to vapor lock.

The solution is to protect the fuel lines from getting hot in the first place.

For carb-equipped vehicles, one of the easiest solutions is to use a t

We’re betting that while you want a thermal barrier that controls heat, you don’t want to puncture the mounting surface or make any modifications in the process. The good news is, Heatshield Products offers several thermal barriers with built-in adhesive backing for easy installation—and one that does not require cutting, modifying or spraying adhesive on anything.

The integral adhesive backing on these products has a special high-temp design that won’t lose its adhesive properties, even after numerous heat cycles and long exposure to heat.

If you’re unsure which thermal barrier is right for your application and heat concerns, use our handy Heatshield Products thermal barrier materials guide. We have explained each product and clearly defined its maximum intermittent and constant-heat exposure temperatures.
